An Iranian mother, whose son was killed after being shot repeatedly at close range by security forces, has been sentenced to 13 years in prison a court after she demanded justice for her child on social media.

According to human rights groups and family members, Mahsa Yazdani, whose 20-year-old son Mohammad Javad Zahedi was killed at an anti-regime protest in September 2022, was convicted on charges of blasphemy, incitement, insulting the supreme leader, and spreading anti-regime propaganda. They say she will serve the first five years with no chance of parole.

After her son was killed, Yazdani publicly condemned the regime’s attacks on protesters and called for justice for her son and others killed in the demonstrations. She was arrested at her home on 22 August.

Hours after the news of the sentence was published, Yazdani’s daughter, Mitra Zahedi, shared a post on Instagram that read: “What will happen to my three-year-old brother? Who is responsible for all this cruelty?”

Videos and photos of her son’s body riddled with shotgun pellets went viral on social media during the mass protests sparked by the death in custody of Mahsa Amini, a young woman who was arrested by Iran’s morality police for not wearing her hijab correctly.
